In the optics lenses
manufacturing process, the accurate measurement of lens distortion is a
delicate process. The way this degradation can be evaluated is through Modulation
Transfer Function (MTF) Measurement. VISIONx
INC. has produced a customized version of VisionGauge®
machine vision software to be used in a sophisticated modulation
transfer function measurement machine.
These customized MTF
measurement systems
support simultaneous image acquisition from 9 cameras,
multiple display modes between which the user can change "on-the-fly",
automatic MTF measurement, automatic PASS
/ FAIL determination, as well as capabilities for accumulating
production & inspection data.
Our systems come with
VisionGauge® OnLine machine vision software which contains highly
accurate measurement tools. With
resolutions up to 0.1 micron (um), the measurement tools provide
accurate results every time.
These tools allow you to perform the numerous types of
measurements, including:
-
Point-to-Point Distance
-
Horizontal Distance
-
Vertical Distance
-
Trace Width (arbitrary orientation)
-
Point-Based Radius or Diameter
-
Angle (4-point)
-
Marker-to-Marker measurements, including fixed
positions, intersection of two lines, center of circle, light-to-dark
and dark-to-light edges, measurements between datums, etc...
Our VisionGauge® software is
proven to be perfect for Modulation Transfer Function (MTF)
Measurement, contact
us for more information on how our machine vision systems
can provide you with the results you need. |
